Any North County or southern Baja vet most likely has run into Garth Murphy intensely evaluating surf conditions from shore and gracefully riding the best waves of the season. A California icon who partnered with Mike Doyle and Rusty Miller in their infamous and pioneering Surf Research company, Garth is the author of the epic novel of California, The Indian Lover, and the son of noted fisheries biologist Garth I. Murphy, who was La Jolla’s Scripps Institution of Oceanography‘s first PhD, and a professor at the University of Hawaii.

Garth Murphy: Because we have 300 wave-rich surf spots to choose from and over a million Southern California surfers average 20 surfs a year – for 20 million yearly immersions in what usually happens to be our ocean’s most bio-diverse coastal marine habitats. The Marine Life Protection Act recognizes traditional surfing as a compatible recreational use of the ocean resource, permitted in protected areas except at mammal haul-outs, bird roosts and estuaries. A network of Marine Protected Areas, by protecting and conserving complete coastal ecosystems and habitat, enhances the biodiversity and abundance of marine life, enriching our experience, while minimizing and controlling potential habitat-destructive human activities, which directly affect us.

Dedina: Why is preserving marine ecosystems of Southern California so important for surfers?

Murphy: Southern California surfers and marine life share natural coastal ocean habitats of every important class: estuaries and river mouths, beaches and inter-tidal zones, surf grass and eel grass beds on composite reefs like Cardiff; rare cobble reefs like Trestles, Rincon and Malibu; rocky reefs like Windansea and Laguna; submarine canyons like Blacks, and sand bars at Newport and Pacific Beach; as well as man-made habitats like the Piers at Huntington and Imperial Beach, rock jetties like the Wedge and Hollywood by the Sea, and artificial reefs.

As a boon to surfers, thick coastal kelp forest canopies, which shelter the greatest biodiversity of coastal marine species, also protect us from the afternoon winds, refining ocean surface texture and grooming the swells to extend our surfing hours and the carrying capacity of affected surf spots. Habitat-based marine protected areas preserve everything within their boundaries, including our cherished surf spots.

Dedina: What about water quality? Would marine reserves help our efforts to keep beaches free from polluted runoff?

Murphy: Coastal ocean water quality is not just a function of land pollution runoff. Over-exploitation and depletion or collapse of important food web components causes imbalances that degrade marine ecosystems and make the ocean more vulnerable to disease outbreaks and opportunistic invasive species like stinging jellyfish, algae blooms and toxic red tides, diminishing water quality and habitat suitability for marine life and surfers.

On the contrary, robust, bio-diverse marine ecosystems with intact food webs are resilient, resisting and adapting to environmental change and pollution, maintaining water and habitat quality. Estuaries are marine life nurseries, fresh/salt water interfaces that empty into many of our finest surf spots. We absorb that same water through our eyes, ears, nose and mouths on duck-dives and wipeouts. Rebuilding and maintaining bio-diverse estuaries with a full range of marine life creates healthier nurseries, and encourages upstream compliance with pollution regulations. The result is better water quality for all of us.

Dedina: So in the end, how does preserving our marine heritage in Southern California benefit surfers?

Murphy: The California surfing style evolved in a unique marine environment of glassy peeling waves. Stylish surfing and our beach lifestyle have become an important part of California history and culture –and media focus – generating an endless wave of glossy-color surf magazines, surf videos and feature films. The success of the $7-plus billion surfing industry, centered in Southern California, depends on maintaining the high cultural value of the traditional California surfing experience: as exciting, invigorating exercise, as a get-away, as a sport, a meditation, a dance, a family get-together and photo opportunity –enhanced by a vibrantly alive and healthy ocean.

The ocean is Earth’s largest and most accessible enduring wilderness. Regular contact with wilderness is a human, and especially American, cultural value, manifested today in the ocean by the popularity of surfing. A full and abundant spectrum of marine species – from whales to hermit crabs to phytoplankton – is an integral part of our ocean-wilderness experience.

Marine Protected Areas enhance ecosystem awareness by exposing us to a broad diversity of marine life. They encourage monitoring of potential problems and upstream compliance with complementary air and water quality regulations. The positive water quality and life-giving effects of marine protected areas are a valuable gift to the surfers and marine species who share them.
